Hi, I'm new to Cassandra and I've recently upgraded to 3.0.0 on Ubuntu Linux 14.04 LTS, through apt-get upgrade not manual installation, after the update all was fine so I could access to my keyspaces using cqlsh but I can't access to Cassandra using DataStax PHP Driver because I get this error: "No hosts available for the control connection”. The connection parameters are the same of 2.2.3 version (and was working fine). I don't know if is this a bug or a problem of the PHP driver but my systems use Cassandra and are now offline, so it's a known issue with a solution? I tried also to downgrade to 2.2.3 version but after that Cassandra didn't start due to keyspace loading problem, I'm just looking for a quick solution so doesn't matter if I have to downgrade to 2.2.3, so how can I do the downgrade without lose my datas? Thanks very much for help!
Best regards, Enrico
